泾阳县水利水保局重视推广科研成果,在机井改建中大力宣传以塑料管代替胶管的好处,积极发展和推广塑料管的使用安装技术,目前“以塑代胶”的机井已达300多眼,收到明显的经济效果。实践证明,“以塑代胶”的好处是:1.水力条件好,管壁摩阻力小,QS25×40-5.5潜水泵可提高装置效率3.3％;4B-15型离心泵装置效率可提高2.36％,从而节省了用电;2.塑料管比胶管价格便宜,4吋塑料管每米17元,只占同样规格胶管价格的
Jingyang County Water Conservancy and Hydropower Bureau attaches great importance to promote scientific research, vigorously promote in the reconstruction of wells to replace the benefits of plastic pipe, and actively develop and promote the use of plastic pipe installation technology, the current “to plastic plastic” machine has reached more than 300 eyes , Received significant economic results. The practice proves that the benefits of “plastic substitution” are: 1. The hydraulic conditions are good, the wall friction is small, the QS25 × 40-5.5 submersible pump can improve the device efficiency of 3.3%; 4B-15 centrifugal pump device can improve the efficiency of 2.36 %, Thus saving electricity; 2. Plastic pipe cheaper than the hose, 4-inch plastic pipe 17 yuan per meter, only the same specifications hose prices
